Pathology is focusing on the nature, cause, origin, and development of diseases. It studies and diagnoses diseases by examing the tissues, shedding cells, bodily fluids, and autopsies. Daan Gene's liquid-based cytology (LBC) preparation systems focus on the examinations of bodily fluids and tissues at the cellular level to screen and diagnose disease and help treatment decision-making. LBC requires sophisticated processing to create slides from liquid specimens. Compared with conventional techniques, using liquid based cytology instrument has a significantly lower unsatisfactory rate and a higher disease detection rate of squamous epithelial lesions. LBC can be a better method of cytological follow-up for post-treated patients with cervical cancer.
